When the external time reference is lost, fallback strategies may be used such as disabling or de-sensitizing the line current differential protection function, switching from the external time reference synchronization mode to a channel based synchronization mode with appropriately selected protection settings, and/or marking the channel as unavailable to isolate the system from the consequences of synchronization errors over this channel and instead using a master-slave mode with other available channels to continue providing line protection with the current differential system. | 2011-03-17 |
20110063767 | CHARGING CURRENT COMPENSATION FOR LINE CURRENT DIFFERENTIAL PROTECTION - Current differential protection with charging current compensation is provided for a power apparatus, such as a power transmission line. Individual terminals dynamically determine their respective contributions, if any, to the charging current compensation value as availability of one or more voltage sources dynamically changes within the power apparatus. Respective terminals calculate local contributions to a charging current compensation value based on local voltage measurements. A loss of a voltage source is handled by adjusting multipliers for the remaining compensation points to reflect the total charging current. A local contribution is suppressed when the local voltage source is no longer available. After applying the local contributions, an alpha plane analysis may be used to determine when to trip the power apparatus. | 2011-03-17 |
20110063768 | ELECTRICAL SAFETY DEVICES AND SYSTEMS FOR USE WITH ELECTRICAL WIRING, AND METHODS FOR USING SAME - Disclosed are systems and methods for monitoring an electrical wire. A safety device utilized to monitor the wire may include at least one current sensing device, at least one voltage sensing device, and at least one processing component. The current sensing device measures a current on at least one conductor of the wire. The voltage sensing device measures a voltage associated with the safety device. The at least one processing component receives the measurements and identifies, based upon the current measurement, an overcurrent event. The processing component then compares the voltage measurement to a stored voltage value and determines, based upon the comparison, that a difference between the voltage measurement and the stored voltage value satisfies a threshold condition. The processing component directs, based upon the determination, at least one relay to be opened to discontinue provision of an electrical power signal onto the electrical wire. | 2011-03-17 |
20110063769 | EQUIVALENT ALPHA PLANE FAULT DETERMINATION FOR A MULTI-TERMINAL POWER APPARATUS - Current differential protection is provided for a multi-terminal power apparatus, such as a power transmission line. Currents measured at each of the multiple terminals are used to calculate a differential current and a restraining current, which are then converted into a first equivalent current and a second equivalent current of an equivalent two-terminal power apparatus. In the equivalent two-terminal power apparatus, a differential current derived from the first and second equivalent currents is substantially equal to the differential current of the original multi-terminal power apparatus. Similarly, a restraining current derived from the first and second equivalent currents is substantially equal to the restraining current of the original multi-terminal power apparatus. The first and second equivalent currents may be used in an alpha plane analysis to determine whether or not to trip the multi-terminal power apparatus. | 2011-03-17 |
20110063770 | SYSTEMS AND METHODS FOR ELECTRONIC WEAPONRY THAT DETECTS PROPERTIES OF A UNIT FOR DEPLOYMENT - An electronic weapon, when combined with a unit for deployment, causes skeletal muscle contractions in a human or animal target. According to the present invention, a launch controller for an electronic weapon includes a detector, a stimulus signal generator, and a switch. When the switch is conducting, it completes a circuit in combination with a unit for deployment. The circuit, when completed, operates a propellant of the unit for deployment to deploy at least two electrodes of the unit for deployment to enable the stimulus signal generator to deliver through the target a stimulus current to incapacitate the target by causing contractions of the skeletal muscles of the target. The detector is coupled to the switch and detects whether the switch is conducting prior to combining the unit for deployment and the electronic weapon. | 2011-03-17 |

20110063772 | METHOD OF DETERMINING A TARGET MESA CONFIGURATION OF AN ELECTROSTATIC CHUCK - A method of modifying the heat transfer coefficient profile of an electrostatic chuck by configuring the areal density of a mesa configuration of an insulating layer of the chuck is provided. A method of modifying the capacitance profile of an electrostatic chuck by adjustment or initial fabrication of the height of a mesa configuration of an insulating layer of the chuck is further provided. The heat transfer coefficient at a given site can be measured by use of a heat flux probe, whereas the capacitance at a given site can be measured by use of a capacitance probe. The probes are placed on the insulating surface of the chuck and may include a plurality of mesas in a single measurement. A plurality of measurements made across the chuck provide a heat transfer coefficient profile or a capacitance profile, from which a target mesa areal density and a target mesa height are determined. The target density and height are achieved mechanically; the target density by mechanically adjusting the areal density of existing mesas; and the target height by creating or deepening low areas surrounding planned or existing mesas, respectively. This can be accomplished using any of known techniques for controlled material removal such as laser machining or grit blast machining on an X-Y table. | 2011-03-17 |
